Embodiment 1

[0018] Take polishing powder samples LCF-A116, LCF-A1171, LCF-A01, LCF-A06, LCF-A106, LCF-A01L, LCF-A151 for corresponding detection, followed by the following steps:

[0019] (1) Pre-dry at 150°C for 30 minutes, weigh 10 grams, add it to a 100mL graduated cylinder, add pure water to 100mL, cover it, and oscillate to fully disperse the polishing powder.

[0020] (2) After standing still for 5 minutes, oscillate again to fully combine the active centers in the polishing powder with water, and then measure the conductivity immediately.

[0021] (3) Carry out the removal rate experiment on the above samples respectively. See the table below for the results:

[0022] Table 1. Comparison of electrical conductivity and removal rate of different samples

[0023]

[0024]

[0025] In the above table, the abrasion hardness of K9 glass is 100, the abrasion hardness of BaK1 is 80, the abrasion hardness of ZK4 is 79, the abrasion hardness of ZK5 is 71, and the abrasion hardness of...

Embodiment 2

[0027] Take the polishing powder sample LCF-A116 of different batches of the same brand for corresponding testing, and follow the steps in turn:

[0028] (1) Pre-dry at 150°C for 30 minutes, weigh 10 grams, add it to a 100mL graduated cylinder, add pure water to 100mL, cover it, and oscillate to fully disperse the polishing powder.

[0029] (2) After standing still for 5 minutes, oscillate again to fully combine the active centers in the polishing powder with water, and then measure the conductivity immediately.

[0030] (3) Carry out the removal rate experiment on the above samples respectively. See the table below for the results:

[0031]

[0032]

[0033] It can be seen from the above table that the difference in conductivity of the four batches of LCF-A116 polishing powder 12-06-1, 12-06-5, 12-06-8, and 12-06-9 is less than 5μs / cm, The difference in the removal rate of the same type of glass does not exceed 0.02 μm / min; when the difference in electrical conductivi...

Embodiment 3

[0035] Take the polishing powder sample LCF-A1171 of different batches of the same brand for corresponding testing, and follow the steps in turn:

[0036] (1) Pre-dry at 150°C for 30 minutes, weigh 10 grams, add it to a 100mL graduated cylinder, add pure water to 100mL, cover it, and oscillate to fully disperse the polishing powder.

[0037] (2) After standing still for 5 minutes, oscillate again to fully combine the active centers in the polishing powder with water, and then measure the conductivity immediately.

[0038] (3) Carry out the removal rate experiment on the above samples respectively. See the table below for the results:

[0039]

[0040]

[0041] From the above table, it can be found that the difference in conductivity of the four batches of LCF-A1171 polishing powder 12-08-119, 12-08-126, 12-08-132, and 12-08-146 is less than 5μs / cm, The difference in the removal rate of the same type of glass is not more than 0.02 μm / min; when the difference between the...

Abstract

The invention relates to a method for guiding polishing powder production and product quality control by using electric conductivity, belonging to the technical field of polishing powder production. The method comprises the following steps of: firstly, accurately weighing 10g of pre-baked polishing powder, adding the weighed pre-baked polishing powder into a 100ml measuring cylinder, adding pure water into the measuring cylinder till the total volume of 100ml is reached, capping and ultrasonically oscillating to fully disperse the polishing powder; and standing for 5min, ultrasonically oscillating the polishing powder again to enable an active center in the polishing powder to be combined with water sufficiently, and then detecting the electric conductivity immediately. For a polishing powder sample detected according to the invention, in terms of an electric conductivity range, the polishing powder with the electric conductivity below 30us / cm is high in polishing rate and good in applicability when polishing materials with the abrasion hardness being 80 and above, and the polishing powder with the electric conductivity above 50us / cm is high in polishing rate and good in applicability when polishing materials with the abrasion hardness below 80.

Description

technical field [0001] The invention relates to a method for guiding the production of polishing powder and controlling the product quality by electric conductivity, and belongs to the technical field of polishing powder production. Background technique [0002] At present, after the production of polishing powder is completed, the characterization of product quality is mainly controlled by particle size. Usually, D100 is used to control the polishing accuracy of the product, and D50 is used to characterize the particle size of the product. However, polishing powder with the same particle size precision is not suitable for glass of various materials. Generally, relatively hard polishing powder is suitable for hard glass polishing, while soft polishing powder is suitable for soft glass polishing, but polishing The detection of the hardness of powders such as powder is still one of the internationally recognized problems. Also, due to slight changes in raw materials or proces...
